bffdc36c38 Add a note about how the "isFile" check in Path::eraseFromDisk prevents 
the erasure of non-file paths like /dev/null.

7e79b3898d Changes: 
1. Update an obsolete comment.
  2. Make the sorting by base an explicit (though still N^2) step, so
     that the code is more clear on what it is doing.
  3. Partition uses so that uses inside the loop are handled before uses
     outside the loop.

Note that none of these changes currently changes the code inserted by LSR,
but they are a stepping stone to getting there.

This code is the result of some crazy pair programming with Nate. :)

880ddb018a Speed up Loop::isLCSSAForm by using a binary search and single-entry cache. 
This reduces LCSSA pass time from 1.5s to 0.96s when run on eon in release+asserts mode.

d41ae8bc0c Replace the SSA update code in LCSSA with a bottom-up approach instead of a top 
down approach, inspired by discussions with Tanya.

This approach is significantly faster, because it does not need dominator
frontiers and it does not insert extraneous unused PHI nodes.  For example, on
252.eon, in a release-asserts build, this speeds up LCSSA (which is the slowest
pass in gccas) from 9.14s to 0.74s on my G5.  This code is also slightly smaller
and significantly simpler than the old code.

Amusingly, in a normal Release build (which includes the
"assert(L->isLCSSAForm());" assertion), asserting that the result of LCSSA
is in LCSSA form is actually slower than the LCSSA transformation pass
itself on 252.eon.  I will see if Loop::isLCSSAForm can be sped up next.

f76d180c95 Fix PR850 and CodeGen/X86/2006-07-31-SingleRegClass.ll. 
The CFE refers to all single-register constraints (like "A") by their 16-bit
name, even though the 8 or 32-bit version of the register may be needed.
The X86 backend should realize what is going on and redecode the name back
to its proper form.
